Step-by-step explanation:
<h2><em>Factor the </em><em>expression</em></h2>

<h2><em>Separate into possible cases</em></h2>
<em>
</em>
<h2><em>Solve the equation</em></h2>
<em>
</em>
<h2><em>Find the union</em></h2>
<em>
</em>
<h2><em>there </em><em>for </em></h2>

The linear model of this case takes the form:
y = a(x-b) + k
<span>The cost of having a package delivered has a base fee of $9.70
this is "k" >>>>> k=9.7 (fixed amount of fee)
THEN
</span>
<span>Every pound over 5 lbs cost an additional $0.46 per pound
that means: 0.46(x-5)
in other words, if the package weighs foe example 9 pounds, then 9-5=4, it will cost 0.46*4 for these 4 extra pounds
Finally we have the linear form of this: C = 0.46 (W - 5) + 9.7
</span>
perimeter means add the side
(x+4) +( x+8)+(2x-3) =P
x+x+2x+4+8-3=P
4x-9 =P
